not RIR but maybe some production red...
and I dont see the EE you speak of... I have EEs and I dont see muffs or beards..... of course there are some w/o but it's not very common.
(you totally didnt ask this but the other two in the last pic look light brahama and black cochin to me... hehe.... testing my breed knowledge... lol. )

Here is what I say officially:

#3 is a polish or polish mix.
#1 is definately part cochin but looks like it may have some wheaten mixed in... possibly.... but it is a cochin mix for sure.
#4 and #5 LOOK like cochin mixes as well but I cant tell if they have feathered legs....
#2 and #6 I havent a clue LOL
